On October 15 2025, parts of Klang Valley and Johor Bahru were plunged into darkness after a lightning strike hit Malaysia’s largest gas-fired power plant in Melaka. The incident, reported by The Edge Malaysia, disrupted power supply for more than an hour — affecting major landmarks such as Mid Valley Megamall, The Exchange TRX, and Pavilion Damansara Heights.

While Tenaga Nasional Berhad (TNB) has since restored power, the sudden blackout served as a wake-up call for both homeowners and businesses:
In a world where power interruptions can happen without warning, a solar battery backup system can prove invaluable.
How Solar Battery Backup Keeps You Powered During Blackouts?
If you already have solar panels, you might assume they’ll keep generating power during a blackout. Unfortunately, standard grid-tied systems automatically shut down when the grid goes offline — a safety feature known as anti-islanding.
However, when paired with a solar battery system, your solar setup can seamlessly switch into off-grid mode, providing uninterrupted electricity for your essential devices and appliances.
A Hoymiles solar battery system, for instance, is designed for blackout protection. Using a hybrid inverter, it automatically switches to battery power in under 10 milliseconds — fast enough that you won’t even notice the change.
How It Works?
1. Seamless switching
When the grid fails, the Hoymiles hybrid inverter automatically transfers your home or business to battery power in less than 10 milliseconds.
2. Backup power mode
You can easily set the system to “Backup Mode” using the Hoymiles app, ensuring your critical loads stay powered.
3. Battery State of Charge (SOC)
Set a minimum SOC level (e.g. 70%) to preserve power for emergencies, so your battery doesn’t fully drain during long outages.
4. Smart battery management
Each Hoymiles system includes built-in safety features — from over-temperature to over-voltage protection — managed by an intelligent Battery Management System (BMS).
5. Real-time monitoring
Track your system’s performance anytime through the S-Miles Cloud app, giving you full visibility over charging, discharging, and backup status.
Backup Solution For Every Home
The Solar Battery Backup System gives you complete control over your home’s energy. It stores excess solar power for use at night or during power outages, delivering reliable backup, lower electricity costs, and true energy independence — all without the noise, fumes, or fuel of a generator.
Whole-House Backup: Keep your air-conditioner, fridge, Wi-Fi, and lights running during blackouts.
Energy Independence: Ideal for off-grid homes, rural areas, and Airbnb stays.
Quiet & Clean Alternative: No noise, no emissions — unlike diesel generators.
Maximize Your Solar: Store unused solar for night-time or cloudy days.
Commercial Battery Energy Storage System (BESS)
A Battery Energy Storage System (BESS) empowers your business with reliable backup power and optimized energy use during peak demand or outages. The result: reduced utility costs, seamless operations, and sustainable energy resilience — without relying on fuel-driven generators.
Emergency Backup : Provides uninterrupted power during grid outages, protecting critical operations.
Spinning Reserve Displacement: Acts as a fast-response energy buffer, replacing traditional spinning reserves and minimizing energy waste.
Solar Ramp Rate Control: Smooths solar output fluctuations by storing and releasing energy during variable production.
Peak Shaving : Reduces Maximum Demand (MD) charges by discharging stored energy during peak hours, improving grid stability.
Off-Grid & Microgrid Ready: Ideal for remote operations (e.g., plantations, mines, and industrial sites) where grid access is limited or diesel reliance is high. Enables cost-effective microgrid solutions.
Why Energy Storage Matters More Than Ever
The Melaka power plant trip took out more than 10% of Peninsular Malaysia’s total power supply — a stark reminder that even a single event can disrupt thousands of homes and businesses.
With a solar battery backup system, you gain:
Continuous electricity during outages.
Reduced reliance on the grid and volatile energy sources.
Energy savings by storing excess solar energy during the day for use at night.
Peace of mind, knowing your operations or comfort won’t be interrupted.
Be Ready Before the Next Outage
Blackouts can strike anytime — but you don’t have to be left in the dark. Whether you’re powering a home, office, or retail space, Solartech’s range of energy storage solutions ensures you stay connected when it matters most.
